摘　　要：为探讨生物质固体成型燃料的能源效率和温室气体排放量,采用全生命周期评价分析原理,对北京地区以玉米秸秆为原料的生物质固体成型燃料进行全生命周期分析。结果表明:生物质固体成型燃料的净能量为13243.5MJ/t,能量产出投入比为10.8,其中,种植阶段、加工阶段以及秸秆运输能源消费居前三位,分别占总量的58.65%、24.23%、12.58%。CO2当量排放量为11.13g/MJ,约为煤的1/9。这说明生物质固体成型燃料具有较大的节能、减少温室气体排放的效益。This study aimed to investigate energy efficiency and greenhouse gas emission. Utilizing system BSAS, using corn stalk as raw material in Beijing Area, It was LCA of densified biofuel and the results showed that the Process of LCA earned 13243.5MJ/t net energy and energy input-output ratio has been arrived about 10.8, among them, planting phase, processing phase and corn stalk transportation were high-overall energy consumption, and case percentages were 58.65% , 24.23% and 12.58%. Greenhouse gas emission was 11.12g/MJ, only one nine. Speak volumes for densified biofuel have benefit of energy saving and emission reduction, it provide evidence for national policy making.
